I have a Mac Pro 1,1. It's been a reliable old work horse for the last nine years or so, but in the last fortnight it's exhibited some worrying behaviour. First one of my internal drives started playing up, which I isolated by realising that when editing with media on that drive, Avid would freeze up. Moving media off that drive and not using it has resolved that problem. However, on a couple of occasions the computer has restarted without warning. Straight to black monitors and the startup chime plays. Once or twice it has happened while the computer was starting up, and another time just as I was about to start working. It hasn't happened after the computer has been on for a while. But once I left the machine alone for an hour or two, came back to find an unusual error message on the screen, which was a semi-transparant grey box (not a normal dialog box window with OK button) telling me I needed to restart the machine by holding down the power button for five seconds (or something to that effect). The message was in about five different languages. So what do you all think? Is this Mac Pro telling me it's time to buy a new one? Or is it maybe related to the dicky drive? Advise away!
